Promise Technology has announced that its Apollo Cloud 2 Duo network attached storage device has received a software update to allow it to appear in the iOS 11 Files application for seamless transfer of files to and from the device from both the Mac and an iPhone or iPad.

The Apollo Cloud 2 Duo hardware itself features a dual-core processor. The unit comes in one configuration with dual-4TB "surveillance-class" hard drives which can be configured in RAID 0 or 1 configurations.

A USB 3.0 type A port allows for backup, transfer, and restore. Network connectivity is provided by a Gigabit Ethernet port. Mac users can use the device as a Time Machine drive, with incremental backups possible over the internet as well.

The Apollo Cloud app allows owners to add up to 40 members to provide a private cloud with no monthly fees. Files can be shared publicly as well to an unlimited amount of people with time-limited links.

Promise's Apollo hardware and software allows for mirroring and backup over the internet.

The update adds Drag and Drop compatibility to the Promise app, as well as full integration with Files, introduced in iOS 11. The app also allows for camera roll backup with sorting of albums by location or facial recognition. Touch ID is supported on the iPhone and iPad.

It is not clear if the Apollo Cloud app update allows for first-generation hardware to use the Files app. AppleInsider has contacted Promise regarding the matter, and will update accordingly.

The Apollo Cloud 2 Duo hardware was released in August. It is now available at Apple Stores for $499, and from other computer hardware vendors.
